“Guardineer’s cover is the earliest Superman cover art in existence,” said Ed Jaster, Senior Vice President at Heritage. “It is a blockbuster piece of early American comic art history and a fitting companion to the landmark finds in this auction.”

Fans who enjoyed the first offering of the Don/Maggie Thompson Pedigree Collection still have a range of high-grade books to choose from with a 9.4 grade CGC NM copy of Tales of Suspense #39, the first appearance of Iron Man.

Surprise discoveries include the finest known copy of Amazing Man Comics #5 (#1), 9.4 CGC Mile High Pedigree, a rare and sought after issue that the Overstreet Price Guide classifies as one of the Top 100 Golden Age books. Fewer than 10 copies of the book exist and this is one of just two copies known in the best condition ever recorded.

The auction also features the Dino Mauricio Golden Age Classic Cover Collection: 150 of the most collectible covers representing important themes, iconic characters and rare images, such as Superman #1 and Detective Comics #31 to rarities like Great Comics #3 with its “Hitler in Hell” cover.
